Loose adaptation of Sylvia Nasar's 1998 bio of Nobel Prize winning mathematician John Forbes Nash Jr. An anti-social genius at Princeton University, Nash wrote his thesis on game theory at 21 and worked for the government in the 1950s before succumbing to paranoid schizophrenia, necessitating his confinement to a mental institution. (The treatment scenes are not for the faint-hearted.) His apparent recovery, after some 30 years, led to sharing a Nobel award in economics in 1994. Director Howard manages to keep the inherent sentimentality and sensationalism generally under control thanks to some powerful performances from Crowe (as Nash), Connelly (as wife Alicia), and Harris (as a sinister government official). The usual controversies swirled about the accuracy of the biopic and what was left out. Ignore the petty carping.
